. Be it known that I, JOHN J. GLEDHILL, a

citizen of the United States of America, and a resident of St.'Louis, Missouri, have invented a certain new and useful Improvement in Vehicles for Carrying Brick, of which the following is a specification.

My invention relates to carts or wagons for carrying brick, and more especially to vehicles which are of a size and character to be pushed or moved around by hand, whereby a pallet of brick may be readily lifted from its support and carried to another place, the cart or wagon embodying in its construction suitable means for raising and lowering the part of its structure upon-which the pallet of brick is supported, thus permitting the vehicle to be positioned below the pallet of brick to be moved to another place and making it possible to then raise the brick-support of the vehicle, so as to raise the pallet of brick from its temporary resting-place and to then transport and deliver the brick to a suitable supporting structure, after which the vehicle can be drawn out from under the brick thus transported and brought to a new resting-place.

Generally stated, the object of my invention is to provide an improved and highly-efiicient vehicle of the foregoing general character.

Special objects of my invention are to simplify and strengthen the construction of the vehicle; to provide an improved construction and arrangement for raising and' lowering the brick support or structure up on which the bricks rests while supported by the vehicle; to provide an improved construction and arrangement whereby the vehicle may involve a pair of main supporting vehicle-wheels and a third wheel which can rest upon the ground or iioor while the vehicle is traveling in a straight line, but which can be tilted upward when it is desired to turn the vehicle around or change its course of travel, and to provide certain details of construction and features of improvement tending to increase the general efficiency and serviceability of a vehicle of this particularcharacter.

To the foregoing and other useful ends my invention consists in matters hereinafter set lforth and claimed.

convenience in illustration. Fig. 2 is an enlarged detail section on line 2 2 in Fig. 1. Fig. 3 is a plan of the vehicle shown'in Fig, l.

As thus illustrated' my invention comprises a body-frame A, composed of a couple of parallel channel-irons d, the same being arranged with their channeled sides facing downwardly and with upturned end portions a. At each side of the vehicle another channel-iron a2 is laid upon and secured to the top of the adjacent channel-iron a, these channel-irons a2 having raised middle portions a3 and upturned end portions a, it being observed that the channel-irons a and a2 are arranged back to back, so to speak, and secured together by bolts 1 and 2. The upper ends of the portion a4 are connected by transverse or horizontally-extending tie-rods or bolt-like members 3. The axle B, upon the end portions of which are mounted the main vehicle-wheels O, extends transversely across the vehicle at a point between the channel-irons a and a3 and is secured in place by bolts 4. It will be seen that these wheels are arranged at each side of the body-frame and are of a size to support the same in a sufficiently-elevated position.

At its'rear end, the vehicle being in the nature of a push-cart, thebody-frame is provided at each side with castings D, to which is rigidly secured a bail-sha ed handle E, the two castings being rigidy tied together by a long bolt or tie-rod 5. It will be seen that the bolts 2 extend through these castings D and also through the channelirons a and a3, thus binding the whole rmly together. The vertically-extending portions of the said castings and of the channelirons a and a3 are tied together by bolts 6, and at Athis juncture it will be seen that the solid and vertically-disposed guides F are disposed in the channels of the upturned end portions a" and are secured therein by the bolts 6. These guides preferably extend upwardly a short distance above the upper ends of the portions a4. At its forward end the body-frame is provided with a pair of castings G, one at each side, and these caste ings are secured to the upturned end portions a and a4 of the channel-irons by means of bolts 7. At this end thebody-frame is provided with vertically-disposed guides H, similar to the guides F and secured in place by the bolts 7. These guides, like the guides F, preferably extend upwardly'a short distance above the upper ends of the vertical portions a4. The two castings G are preferably tied together by a long bolt or tie-rod 8.

lt will now be seen that the third and relatively small vehicle-wheel I is mounted to rotate upon the bolt or tie-rod 8, while the operating-lever J is fulcrumed to turn upon the bolt or tie-rod 5. Preferably the wheel I and the hand-lever J are disposed in line with each other and at points substantially midway between the two sides ofv the vehicle.

The vertically-movable brick-support K comprises two parallel channel-irons k, one at each side of the vehicle, and arranged with their channels facing downward and with downwardly-bent end portions c. These downwardly-bent end portionslc are adapted toslide up and down on the guides F and H, as shown more clearly in Fig. 2. Each channel-iron lc is provided on its under side with front and rear castings 762 and k3, the same being secured in place by bolts 9 and 10, as shown in Fig. 1. At this juncture it will also be seen that the bolts 1 are employed for securing similarcastings a5 to the under sides of the channel-irons a and that the bolts 2 assist in securing'the castings D to the same channel-irons. The brick-support K is raised and lowered by four toggle connections, two at each-side, the castings (L5 being connected with the casting k2 by` means of toggle-arms L and M, which are pivotally connected at their upper and lower ends with the-said castings by means of bolts lland 12. It will also be seen that the meeting end portions of these toggle-arms are connected by means of bolts 13.

At the rear end of the framework of the vehicle the castings D and 7f3 are connected by toggle-arms N and O, the castings being connected to the ends of the arms by pivotbolts 14 and 15 and the lower arms at each side being connected to the upper arms by means or bolts 16. In this way there are, as stated, four toggle .connections between the brick-support K and the body-frame A, it being understood that, through the medium of these toggle connections the brick-support can be raised and lowered, as shown in dotted lines in Fig. 1. At each side the middle portions or knuckle-joints of the toggles are connected by horizontal and longitudinally-disposed connecting-bars P, whereby if one toggle breaks joint in a forward direction the others necessarily follow-that is, the toggles are so connected that they must move in unison. As 'a`n efficient arrangement for operating these toggles the side bars or connecting members P are connected with the hand-lever J by means of a pair of connecting rods or bars Q. It will be seen that these rods or bars Q have their forward or separated ends pivotallv connected with the bars P by means of bolts or pivotal connections 1, while at their rear or convergent ends the said bars or rods Q are pivotally connected to the lever by means of a bolt or pivotal connection g. At this juncture 1t will be seen that the wheel l is prevented from shifting laterally by means of collars i,

attached to the tie-bolt or long bolt 8, upon which the said wheel is mounted, the two collars being of course disposed at opposite sides of the wheel, and in a similar way the mounted or hub portion of the hand-lever J is prevented from shifting laterally upon the bolt or tie-rod 5 by means of collars y, which are lixed to the said rod or bolt at each side or the lever.

The stationary side portions of the bodyframe A are not only c onnected at the forward end of the vehicle by the rod or tiebolt 3, but are also connected at the rear end of the vehicle by a similar rod or tiebolt 17, the latter `extending through the upper ends of the portions d4. It will be readily understood that the rods or bolts 3,

5, 8, and 17 may all be provided at their end portions with suitable nuts adapted to clamp o`n both sides of the stationary or rigid side members of the frame or body A, as-shown more clearly in Fig. 3.

With this construction the brick-support K can be lowered by throwing the handle upward and into the approximately vertical position shown in Fig. 1. In such condition the vehicle can be positioned beneath a pallet of brick, andl such pallet of brick can then be lifted from its stationary supporting structure by swinging the handle positioned as shown in dotted lines in Fig. l. lVhen the handle is raised for the purpose of lowering the brick-support, all of the toggle connections are compelled to break joint in a forward direction-that is, in a direction toward the forward or front wheel I; but when the handle J is pulled down into the position indicated the said toggles are then all straightened out7 and the movement is preferably just sufficient to cause said toggles tobreak joint slightly in a rearward direction, as shown in dotted lines in Fig. 1, as by so doing the knuckle-joints-of the toggles arel moved slightly past the center, thus retaining the brick-support in its raised position. Raising the brick-support raises the pallet of brick from its supporting structure, as stated, and in such condition the vehicle can thenv be pushed forward or drawn in the opposite direction, according to the convenience of the operator. When the desired position for the pallet of brick. is reached-as, for eX- ample, by wheeling the vehicle between a couple of supporting members-the handle J can then be thrown into its raised position, thus lowering the brick-support K and allow- IOO ing the pallet of brick to go down and rest upon said supports arranged at each side of the vehicle.

During the movements or use of the vehicle the front wheel I, which has its axis rigidly connected with the body-frame A, can be tilted oi from the ground, so as to make it easy to turn the vehicle around or to alter its course of travel. In this connection it will be observedthat the axle B is preferably somewhat nearer the rear or handle end of the body-frame, thus throwing considerable weight upon the wheel I when the latter is upon the ground-that is to say, the position of the axle is such that the weight of the brick upon the vehicle has no tendency to tilt the wheel I upward and away from the ground, although ofcourse the vehicle is preferably so nearly balanced upon its axle that it is very easy for the operator to tilt the said Wheel I off the ground by simply bearing down upon the handle E.

When the brick-support K is held in its raised position, it is prevented from fallingthat is, the toggles are prevented from breaking joint in a forward and rearward direction by the'engagement of the end of the handle J with the cross-piece of the bail-shaped pushing-handle E. In other words, this handle J can swing downward as far as the position indicated in dotted lines in Fig. 1, and when it reaches such position the centers of the toggles are just past the center 'in a rearward direction and can 4move no farther in such direction. In this way the brick-support K is very easily raised and lowered, the

portions k sliding freely and accurately upon thesolid guide-posts or guides H and F,

. which guides constitute upright portions oi' the rigid body-frame A, inasmuch as they are arranged at the four corners of the vehicleframe and rigidly connected with the parallel and horizontal and longitudinally-disposed channel-irons which constitute the stationary or rigid body portion of the vehicle.

What I claim as my invention is-'- 1. A vehicle for carrying brick, comprising a rigid body-frame mounted on wheels, a bail-shaped handle rigidly secured to one end of said body-frame, a brick-support mounted to slide up and down on said body-frame, a

plurality of toggle connections connecting the brick-support to the body-frame, said toggle connections being adapted to break joint away from the handle in order to lower the brick-support, and adapted to break joint in a direction toward the handle for the purpose of retaining the brick-support in a raised` position, and a hand-lever associated with said pushing-handle and connected for operating said toggles.

2. A vehicle for carrying brick, comprising a body-frame mounted on wheels, a bricksupport `mounted to slide up and down on said body-frame, a plurality of toggles arranged at one side of the vehicle and adapted for connecting the body-frame to the bricksupport, a plurality of similar toggles arranged at the other side of the vehicle and also adapted for connecting the brick-support with the body-frame, a bar at one side oi' the vehicle for connecting the toggles at that side, a bar i'or connecting the toggles at the other side of the vehicle, a handle rigidly connected with the body-frame, and a pivoted hand-lever associated with said handle and connected with said bars, whereby the brick-support can be raised and lowered by operating said hand-lever, said toggles being adapted to break joint in a direction away from the handle and hand-lever when the brick-support is lowered.

3. A vehicle for carrying brick, comprising a body-frame composed of parallel and longitudinally-arranged channel-irons, one channel-iron being arranged on top of the other at each side of the vehicle, an axle extending across and secured between the said upper and lower channel-irons, said channelirons having their front and rear ends upturned and provided with vertical guides, wheels mounted on said axle, a brick-support composed of parallel and longitudinallydisposed channel-irons having their end portions bent down and adapted to slide up and down on said guides, toggles connecting the brick-support with the body-frame, a handle rigid with the body-frame, and a swinging hand-lever connected for operating said toggles, whereby the brick -support can be raised and lowered by operating the handlever.

4. A vehicle for carrying brick, comprising a body-frame, an axle extending transveresly of the body-frame, vehicle-wheels mounted on the ends of the axle, a pair of castings secured to the forward end of said body-frame, a bolt or tie-rod connecting said castings, a third wheel mounted upon said bolt or tierod, castings secured to the other endoi the body-frame, another bolt or tie-rod connecting said last-mentioned castings, a bailshaped handle rigidly secured to said lastmentioned castings, a hand-lever fulcrumed on said last-mentioned bolt or tie-rod, and a brick-support mounted to slide up and down upon the body-frame and suitably connected to be operated by said hand-lever.
